Who are we?

At Antioch, we’re building the future of robotics development: a unified platform where teams can design, train, and test full-scale robots in high-fidelity cloud simulation—then deploy to real hardware with confidence.

We work with many of the world’s leading robotics, autonomy, and perception teams to make deploying autonomous systems safer, faster, and more cost-effective.

For us, high-fidelity simulation isn’t just visual polish. Our environments must be physically and sensor-real: accurate masses, meshes, rigid bodies, inertias, and realistic sensor models across cameras, radar, lidar, infrared, depth, and more.

Who are we looking for?

We’re looking for 3D Asset Artists / Technical Artists (USD / Omniverse / Isaac Sim) to help build the content that makes our simulation believable, performant, and reusable.

You’ll create scenes, objects, and animated agents—humans, animals, vehicles, robots, and props—that combine into rich, modular digital worlds: homes, warehouses, factories, dense urban environments, oceans, and beyond.

Your work at Antioch will be used by some of the world’s foremost Physical AI teams—companies transforming manufacturing, logistics, construction, safety, and more.

What you’ll do

1. World building (scenes & environments): Create high-quality, simulation-ready environments (indoor/outdoor), layout, dressing, and set assembly — often based on real-world settings provided by our customers.

2. Asset creation (props, vehicles, agents): Model/UV/texture objects ranging from small props to complex vehicles and characters/creatures.

3. Animation & agents: Rig and animate assets where needed (loops, locomotion, interactions), and ensure they play cleanly in our sim stack.

4. USD pipeline ownership: Author, assemble, and maintain assets in a USD-first workflow (hierarchy, variants, references/payloads, instancing, LODs, etc.). In particular, meeting NVIDIA SimReady guidelines (https://www.nvidia.com/en-us/glossary/simready/).

5. Sensor-real materials: Tune assets so they behave realistically under camera + radar + lidar + infrared simulation—helping to refine materials, roughness/specularity, emissives, translucency, normal detail, and any sensor-facing metadata/workflows we use.

6. Simulation readiness: Build collision, physics proxies, scaling, pivots, naming conventions, and performance constraints so assets are robust in real-time rendering.

7. Library building: Help us create a curated, consistent asset library (standards, templates, validation checks, documentation), with variants built in (the ability to tune factors and apply domain randomizations such as time of day, lighting conditions, and more).

8. Represent and build Antioch: You’ll be a key representative of Antioch in customer conversations, site visits, and more, playing a core role in how we build.

Tooling expectations

• Use whatever tools you think are best (Blender/Maya/3ds Max/Houdini/Substance/etc.).

• We’re opinionated about your output, not your process: we expect deliverables to ship as USDZ (for use with NVIDIA Omniverse / Isaac Sim), with a clean USD structure (variants/LODs as appropriate) and assets ready to drop into simulation.

You may be a great fit if…

1. You’re high-agency and take pride in shipping assets that are not just beautiful, but correct.

2. You can take loose requirements (“we need a factory floor that works for lidar”) and turn them into solid, reusable deliverables.

3. You’re passionate about playing a critical role in building a category-defining business.

4. You balance craft and pragmatism; you strive for excellence, but recognize when “good enough now” beats “perfect later”, and work with your team to figure out which is which.

5. You embrace uncertainty, autonomously search for answers, and are comfortable diving into unfamiliar tools/pipelines to solve a problem.

What we’re looking for (baseline requirements)

1. Strong portfolio demonstrating scene creation and asset production (props + environments; bonus for vehicles and characters/creatures).

2. Experience creating assets that meet NVIDIA’s SimReady guidelines (https://www.nvidia.com/en-us/glossary/simready/)

3. Comfort with real-time constraints: sensible poly budgets, texture budgets, LODs, instancing, and scene organization.

4. Experience with PBR materials and a workflow that translates well to Omniverse (e.g., MDL / USD Preview Surface pipelines).

5. Proven ability to deliver assets that are simulation-ready: correct scale/units, pivots, naming, clean geometry, collision proxies, and predictable transforms.

6. Experience (professional or deep hobbyist) tuning materials/assets for sensor realism (especially camera, lidar, radar, and infrared).

Nice-to-haves

1. Direct experience with NVIDIA Omniverse and/or Isaac Sim.

2. Technical art chops: Python tooling, pipeline automation, exporters, validators, asset conditioning.

3. Motion capture, retargeting, blendshapes, or procedural animation.

4. Photogrammetry/scans and cleanup for simulation-grade assets.

5. Prior work on simulation, robotics, autonomy, synthetic data generation, or VFX-to-real-time pipelines.

6. Expertise in Gaussian splatting and other generative 3D modelling approaches.

What “good” looks like at Antioch

1. Creating assets that look great, and hold up to scrutiny by various different types of sensors.

2. Creating assets that load fast, run in real-time (or faster),

3. Delivering USDZ files that are clean, consistent, and easy for engineering to consume.

4. Embodying a builder mindset: you leave all aspects of product and process better than you found them.

Our hiring process

• Application review

• Intro call

• Portfolio deep-dive (we’ll look at scenes and how you build them)

• Practical exercise (paid): deliver a small USDZ asset set with materials + collisions + basic LODs, validated in an Omniverse-compatible workflow

• Final convo with the team
